That seems to be a mix of ignorance and incompetence, weighted towards incompetence.

Ignorance, ie. 'I can see why you might spell it that way':

• translucient
• translurcent (made me laugh)
• transluscent
• transluscient

Incompetence, ie. 'you either fail at pronunciation, were typing too fast, or aren't even trying'

• transluctant
• transluent
• traslucent
• trnaslucent
• trabslucent
• trsnalucent
• transllusent
• transluceent

If I were an admin, I'd probably make aliases for the items in the 'ignorant' list in advance...

And maybe alias the items on the 'incompetent' list to 'invalid_user' ;)
